Trait std::os::unix::io::IntoRawFd

Consumes this object, returning the raw underlying file descriptor.

This function transfers ownership of the underlying file descriptor to the caller. Callers are then the unique owners of the file descriptor and must close the descriptor once it’s no longer needed.

Example

use std::fs::File;
#[cfg(unix)]
use std::os::unix::io::{IntoRawFd, RawFd};
#[cfg(target_os = "wasi")]
use std::os::wasi::io::{IntoRawFd, RawFd};

let f = File::open("foo.txt")?;
#[cfg(any(unix, target_os = "wasi"))]
let raw_fd: RawFd = f.into_raw_fd();
